your area. To avoid distracted driving, always keep your eyes on the road, hands on the wheel, and mind on the drive. . Do not use a phone in
demanding driving situations. Use a hands-free method to place or receive necessary phone calls.
. Watch the road. Do not read,
take notes, or look up information on phones or other electronic devices.
. Designate a front seat
passenger to handle potential distractions.
. Become familiar with vehicle
features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving.
. Wait until the vehicle is parked

Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the safety belt. See Safety Belts 0 80. . Assume that other road users
(pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready.
. Allow enough following distance
between you and the driver in front of you.
. Focus on the task of driving.
Drunk Driving Death and injury associated with drinking and driving is a global tragedy.
{ Warning
Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink.
Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.
Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.
Driving and Operating
229
Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency. Helpful braking tips to keep in mind include: . Keep enough distance between
you and the vehicle in front of you.
. Avoid needless heavy braking. . Keep pace with traffic. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push.

Driving and Operating
Steering
Electric Power Steering This vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required. If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort. See your dealer if there is a problem. If the steering assist is used for an extended period of time, power assist may be reduced. If the steering wheel is turned until it reaches the end of its travel, and is held in that position for an extended period of time, power steering assist may be reduced. Normal use of the power steering assist should return when the system cools down. See specific vehicle steering messages under Steering System Messages 0 169. See your dealer if there is a problem.
Curve Tips . Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of the curve before accelerating gently into the straightaway.
Steering in Emergencies . There are some situations when steering around a problem may be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn 180 degrees without removing a hand.
. Antilock Brake System (ABS) allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement.
2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
3. Turn the steering wheel to go
straight down the roadway.
Loss of Control
Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a curve causes tires to slip and lose cornering force.
. Acceleration Skid — too much
throttle causes the driving wheels to spin.
Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the
accelerator pedal and steer the way you want the vehicle to go.
The vehicle may straighten out. Be ready for a second skid if it occurs.
. Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.
Remember: Antilock brakes help avoid only the braking skid.
Off-Road Driving Four-wheel-drive vehicles can be used for off-road driving. Vehicles without four-wheel drive and

vehicles not equipped with All Terrain (AT) or On-Off Road (OOR) tires must not be driven off-road except on a level, solid surface. For more contact information about the original equipment tires, see the Limited Warranty and Owner Assistance Information manual. One of the best ways for successful off-road driving is to control the speed.
{ Warning
When driving off-road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear safety belts.
Before Driving Off-Road . Have all necessary maintenance
and service work completed.

232
Driving and Operating
. Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped.
. Read all the information about
four-wheel-drive vehicles in this manual.
. Know the local laws that apply to
off-road driving.
To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam. However, driving without the air dam reduces fuel economy.
Caution
Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper air flow to the engine. Re-attach the front fascia air dam after off-road driving.
Loading the Vehicle for Off-Road Driving
{ Warning
. Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly.
. Keep cargo in the cargo
area as far forward and as low as possible. The heaviest things should be on the floor, forward of the rear axle.
. Heavy loads on the roof
raise the vehicle's center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof.
For more information about loading the vehicle, see If the Vehicle Is Stuck 0 238 and Tires 0 351. Environmental Concerns . Always use established trails,
roads, and areas that have been set aside for public off-road recreational driving and obey all posted regulations.
. Do not damage shrubs, flowers,
trees, or grasses or disturb wildlife.
. Do not park over things that
burn. See Parking over Things That Burn 0 253.
Driving on Hills Driving safely on hills requires good judgment and an understanding of what the vehicle can and cannot do.
{ Warning
Many hills are simply too steep for any vehicle. Driving up hills can cause the vehicle to stall. Driving down hills can cause loss (Continued)
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
Warning (Continued)
of control. Driving across hills can cause a rollover. You could be injured or killed. Do not drive on steep hills.
Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further. When driving on hills: . Use a low gear and keep a firm
grip on the steering wheel.
. Maintain a slow speed. . When possible, drive straight up
or down the hill.
. Slow down when approaching
the top of the hill.
. Use headlamps even during the
day to make the vehicle more visible.
{ Warning
Driving to the top of a hill at high speed can cause an accident. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert.
. Never go downhill forward or
backward with either the transmission or transfer case in N (Neutral). The brakes could overheat and you could lose control.

transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to P (Park). Shift the transfer case to any position but N (Neutral).
. When driving down a hill, keep
the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control.
{ Warning

descending a hill and use a low gear to keep vehicle speed under control.
If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake.
2. Shift into P (Park) and then
restart the engine.
If driving uphill when the vehicle stalls, shift to R (Reverse), release the parking brake, and back straight down.
. Never try to turn the vehicle
around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. If you cannot make it up the hill, back straight down the hill.
. Never back down a hill in N (Neutral) using only the brake. The vehicle can roll backward quickly and you could lose control. If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill.
If the vehicle cannot be restarted after stalling, set the parking brake, shift into P (Park), and turn the vehicle off. 3.1. Leave the vehicle and
seek help.
3.2. Stay clear of the path the
vehicle would take if it rolled downhill.
3.
. Avoid turns that take the vehicle
across the incline of the hill. A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the
downhill wheels, which could cause a downhill slide or a rollover.
. Surface conditions can be a
problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it — a rock, a rut, etc. — and roll over.
. Hidden obstacles can make the
steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more. If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
{ Warning
Getting out of the vehicle on the downhill side when stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill side of the vehicle and stay well clear of the rollover path.
Driving in Mud, Sand, Snow, or Ice Use a low gear when driving in mud — the deeper the mud, the lower the gear. Keep the vehicle moving to avoid getting stuck. Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tires tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers.
Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice.
{ Warning
Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice; you and your passengers could drown. Drive your vehicle on safe surfaces only.
Driving in Water
{ Warning
Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires.
(Continued)
Driving and Operating
235
Warning (Continued)
Traction could be lost, and the vehicle could roll over. Do not drive through rushing water.
Caution
Do not drive through standing water if it is deep enough to cover the wheel hubs, axles, or exhaust pipe. Deep water can damage the axle and other vehicle parts.
If the standing water is not too deep, drive slowly through it. At faster speeds, water splashes and the vehicle can stall. When going through water, the brakes get wet and it may take longer to stop. See “Driving on Wet Roads” later in this section.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
236
Driving and Operating
After Off-Road Driving Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires, and exhaust system for damage and check the fuel lines and cooling system for any leakage. More frequent maintenance service is required. See the Maintenance Schedule 0 401.
Driving on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water.
{ Warning
Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally. Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.
Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is
wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. . Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires 0 351.
. Turn off cruise control.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include: . Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and transmission.
. Shift to a lower gear when going
down steep or long hills.
{ Warning
Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.
Driving and Operating
237
{ Warning
Winter Driving
Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering. Always have the engine running and the vehicle in gear.
. Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line.
. Be alert on top of hills;
something could be in your lane (e.g., stalled car, accident).
. Pay attention to special road signs (e.g., falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.
Driving on Snow or Ice Snow or ice between the tires and the road creates less traction or grip, so drive carefully. Wet ice can occur at about 0 °C (32 °F) when freezing rain begins to fall. Avoid driving on wet ice or in freezing rain until roads can be treated.
For Slippery Road Driving: . Accelerate gently. Accelerating
too quickly causes the wheels to spin and makes the surface under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic Stability Control 0 267.
. The Antilock Brake System
(ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry pavement. See Antilock Brake System (ABS) 0 265.
. Allow greater following distance and watch for slippery spots. Icy patches can occur on otherwise

Driving and Operating
clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice.
. Turn off cruise control. Blizzard Conditions Stay with the vehicle unless there is help nearby. If possible, use Roadside Assistance. See Roadside Assistance Program 0 421. To get help and keep everyone in the vehicle safe: . Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{ Warning
Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains
(Continued)
Warning (Continued)
carbon monoxide (CO), which cannot be seen or smelled. It can cause unconsciousness and even death. If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any blocking the exhaust pipe. . Open a window about 5 cm
(2 in) on the vehicle side that is away from the wind, to bring in fresh air.
. Fully open the air outlets on
or under the instrument panel.
. Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.”
For more information about CO, see Engine Exhaust 0 254.
To save fuel, run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps. If it takes time for help to arrive, when running the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible, to save fuel.
If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. See “Rocking the Vehicle to Get It Out” later in this section. The Traction Control System (TCS) can often help to free a stuck vehicle. See Traction Control/ Electronic Stability Control 0 267. If TCS cannot free the vehicle, see “Rocking the Vehicle to Get it Out” following.

causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. See Towing the Vehicle 0 385. Recovery hooks can be used, if equipped. Recovery Hooks
{ Warning
Never pull on recovery hooks from the side. The hooks could break and you and others could be injured. When using recovery hooks, always pull the vehicle from the front.
{ Warning
If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph).
For information about using tire chains on the vehicle, see Tire Chains 0 370. Rocking the Vehicle to Get It Out Turn the steering wheel left and right to clear the area around the front wheels. For four-wheel-drive vehicles, shift into Four-Wheel Drive High. Turn the TCS off. Shift back and forth between R (Reverse) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Slowly spinning the wheels in the forward and reverse directions
Caution
Do not drive through standing water if it is deep enough to cover the wheel hubs, axles, or exhaust pipe. Deep water can damage the axle and other vehicle parts.
If the vehicle has recovery hooks at the front of the vehicle, use them if the vehicle is stuck off-road and needs to be pulled some place to continue driving.

Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on the vehicle may show how much weight it was designed to carry, the Tire and Loading Information label and the Certification/Tire label.
{ Warning
Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a

crash. Overloading can also reduce stopping distance, damage the tires, and shorten the life of the vehicle.
Tire and Loading Information Label
Label Example
A vehicle specific Tire and Loading Information label is attached to the center pillar (B-pillar). The tire and loading information label shows the
number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires 0 351
and Tire Pressure 0 358. There is also important loading information on the vehicle Certification/Tire label. It may show the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certification/Tire Label” later in this section. “Steps for Determining Correct Load Limit– 1. Locate the statement "Thecombined weight of occupants and cargo should

2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals
the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.)

New Vehicle Break-In
Caution
The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines:
. Keep the vehicle speed at
88 km/h (55 mph) or less for the first 805 km (500 mi). . Do not drive at any one
constant speed, fast or slow, for the first 805 km (500 mi). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.
. Avoid making hard stops for
the first 322 km (200 mi) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean

Caution (Continued)
premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings.
. Do not tow a trailer during
break-in. See Trailer Towing 0 299 for the trailer towing capabilities of the vehicle and more information.
Following break-in, engine speed and load can be gradually increased.
Adjustable Throttle and Brake Pedal If equipped, the position of the throttle and brake pedals can be changed. The pedals can only be adjusted when the vehicle is in P (Park).

Caution
If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 309.
Starting Procedure (Key Access) 1. With your foot off the
accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. When the low fuel warning lamp is on and the FUEL LEVEL LOW message is displayed in the Driver
Information Center (DIC), hold the ignition switch in the START position to continue engine cranking.
Caution
Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.
2.
If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there while holding the key in START for up to 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine

Torque Lock If you are parking on a hill and you do not shift the transmission into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To find out how, see Shifting Into Park 0 252. When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake. If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. You will then be able to pull the shift lever out of P (Park).
Shifting out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: . Prevent ignition key removal
unless the shift lever is in P (Park).
. Prevent movement of the shift
lever out of P (Park), unless the ignition is in ON/RUN and the regular brake pedal is applied.
The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery. If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting - North America 0 382. To shift out of P (Park): 1. Apply the brake pedal. 2. Move the shift lever to the
desired position.
